javascript - 解决 index.js 内的 'eslint' 错误 - Angular 5

Question

当我尝试部署 Angular 函数时，出现 eslint 错误。我确定该问题包含在本文中找到的代码片段中:https://medium.com/@markgoho/create-a-contact-form-in-angular-using-cloud-functions-for-firebase-5e390bdf5600

这是我从文章中抓取并放入我的 index.js 文件中的片段:

exports.sendContactMessage = functions.database.ref('/messages/{pushKey}').onWrite(event => {
    const snapshot = event.data;

  // Only send email for new messages.
    if (snapshot.previous.val() || !snapshot.val().name) {
      return;
    }

    const val = snapshot.val();

    const mailOptions = {
      to: 'test@example.com',
      subject: `Information Request from ${val.name}`,
      html: val.html
    };

    return mailTransport.sendMail(mailOptions).then(() => {
      return console.log('Mail sent to: test@example.com')
    });
  });

这是完整的错误输出:

当我删除第 3 方代码片段时，错误就会消失。

我的 JavaScript 知识非常有限，所以我很难找到问题所在。我该如何解决这个问题？

日志建议您验证正在运行的最新节点和 npm。如果您使用的是 Windows，则节点安装还将安装最新的 npm。我建议先尝试一下。

日志建议在这里:

Make sure you have the latest version of node.js and npm installed.

看起来它提到您正在使用 node v6.10.2 并且当前最新的是 v9.5.0
